"I want a game on steam! What should I do?"
Contact the original developers or publishers.

Now, I know, that isn't what you asked, but Planetside 2 is a big AAA title. If it is on PC, and not exclusive to the Origin system, there is an extremely high chance for it to be on steam at some point.

Greenlight is for submitting indie, or single A titles, that are little known, Planetside 2 is VERY known.

thanks, i havent thought of that

FTFY. Also, the movie you are a fan of is called 'Star Wars' not 'starwar'.
